SPECIFICATION forming part of Letters Patent No. 768,779, 'dated August 80, 1904.

Applicatiou'led August 29, 1903. Serial No. 171,312. (No model.)

To all whom, it may concern.'

Be it known that I, HARRY XV. S'roNma citizen of the United States, residing at Brooklyn, in the city of New York, county of Kings, and State of New York, have invented an Improvement in Fountain-Pens, of which the following description, in connection with the accompanying' drawings, is a specification, like letters on the drawings representing like parts.

My invention consists in an improved construction of fountain-pen, being particularly concerned with fountain-pens wherein the writing-pen is projected from or withdrawn into the lower end of the tip or feed section. My invention will be best understood from the following description and accompanying illustration of onespecic embodimentthereof, taken in connection with the accompanying illustrations, while its scope will be more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a longitudinal section of the fountain-pen with the pen eX- tended and ready for writing. Fig. 2 is a similar section showing pen withdrawn within the feed-section. Fig. 3 is a view similar to Fig. 2, showing, however, the cap removed from the top of the penholder and secured over the feed-section. Fig. 4 is a section taken on the line i 4 in Fig. 1.

' In the drawings, a is the pen-barrel containing the ink-reservoir through which extends the pen operating or propelling rod c, provided at its end near the feed-section l with a sleeve or nozzle e, of silver or other suitable material, into which the writing-pen `f is fitted .and by which it is secured to the propelling-rod c. At its opposite or upper end the rod c passes through and is slidable within an ink-tight packing, preferably of cork. This cork packing' g abuts against a suitable surface within the ink-barrel, such as is provided by the fixed Washer 7L, against which it is pressed by the threaded cap a', the latter being provided with a slot j', by which the cap may be screwed within the threaded bore of the barrel end down and against the cork packing to retain the latter in position, as well as to increase the pressure on the packing if the latter or the rod become so worn as to cause leakage. The provision of the slot j permits theV insertion of a screw-driver or other suitable tool within the end of the barrel to effect this latter adjustment or to permit the removal of the cap when necessary.

I have herein shown the surface of the washer/L in contact with the packing as conveX and that ofthe threaded cap z' in contact with the packing as concave. When the cap and washer are brought relatively nearertogether, they not only compress the cork packing, but there is a separate wedging effect eX- erted-thereupon by both the cap and washer. The convex surface'of the washer is so inclined that it causes the packing to be forced or wedged outward against the inner Walls of the barrel, the extentor degree of Wedging force being dependent upon the compression exerted upon the cork and the inclination or radius of curvature of the convex surface, while the oppositely-disposed concave 'surface of the cap similarly forces the packing inward against the rod to better prevent leakageat each surface.

The cap r: is provided with a coupling member Z, projecting from the dome thereof fand iixedly securedthereto, as by the pin m, th'e tip of the member Z, which is within the cap 71, being provided with an internally-threaded recess fa, adapted to engage with' the threaded tip 0 of the operating-rod when the cap is placed upon the upper part of the pen and to be secured thereto by slight twisting movement of the cap. 1

The tip of the feed-section is internally threaded and adapted to engage with correspondingly externally threaded portion p upon the coupling member Z, so that when pen f is in its retracted position, as in Fig. 2, and

the coupling member has been freed from the tip of the propelling-rod through a reverse twisting movement the cap may be placed' over the lower end of the barrel and the feeding-section and secured thereto by securing the tip of the coupling member lirmly into the internally-threaded portion of the feedsection` thereby effectually closing' the inkreservoir and feed-section against the escape of the contents.

When it is desired to employ the pen for writing', after unscrewing the cap from the mouth of the reservoir., the pen then being' held with the mouth upward, the cap is forced over the opposite or upper end of the holder, being' turned slight-ly as the member Z comes in contact with the tip o of the propelling-rod c to screw the one to the other. The rod and the member may then be pushed outward from the position shown in Fig. 2 to that'shown in Fig. l o1' may be pulled backward to retract the pen. as desired, the cap after final use and retraction of the pen being' reversely turned to release the member and the rod and withdrawn from the barrel end, after which it may be used to close the lower or feeding' portion of the pen, as described and as shown in Fig. 3. A pin 0 or other suitable stop limits the outward movement of the rod and pen by contact wi-th an interior shoulder within the barrel, while a stop-pin v' limits the inward or retracted movement of the rod by contact with the washer 71 the latter being' also provided with a slot or recess s, within which the pin 7' seats itself in the retracted position of the rod to prevent the turning' of the latter when it is desired to screw the coupling-pin on or off from the threaded rod-tip.

lVhile the cap r has an easy sliding lit upon the upper barrel end when the pen is closed, it is preferably provided with a close fit in the open position of the pen, as in Fig.l, in order to add the friction thereof to the friction of the rod passing through the cork packing', thus aiding in giving the rod a firm support to maintain the pen in position under all conditions of use.

fit will be obvious that my invention is not limited to the specific details or to the arrangement of parts herein shown for illustrative purposes only, but that the saine may be modified and varied within wide limits without dej'iarting' from the spirit thereof.

VlY claim-V l. A fountain-pen having an extensible pen, a propelling-rod therefor, a slidable pen-propelling' cap adapted to [it over the end of the barrel and there to be secured to the propelling-rod, sliding'movement of the cap effecting` the extension or retraction of the pen froln the holder.

2. A fountain-pen having' an extensible pen, a propelling-rod therefor, a packing' through which said rod extends, and adjustable means for securing' said packing' in position.

A fountain-pen having' an extensible pen, a propelling-rod therefor, a cap adapted to effect the movement of said rod by a longitudinal sliding movement of the cap over the upper end of the penholder, said cap being' also adapted to be secured over the opposite end of the holder to form an ink-tig'ht closure therefor. y

LL. A fountain-pen having' aslidable propelling-rod for projecting' and retracting' the pen, said rod being' non-rotatable only in its retracted position.

A fountain-pen having' a propelling-rod, a coupling member adapted to be screwed thereto and means to secure said rod from 1'0- tation for the attachment thereto or detachment therefrom of said coupling member.

6. A fountain-pen having a packed joint and means for varying the deg'ree of compression upon the packing' thereof.

7. A fountain-pen having' a barrel, a propelling-rod, a packed joint between said rod and barrel, suitable packing' therefor. and means for forcing' said packing' laterally ag'ainst the rod and also laterally against the inner walls of the barrel.

8. A fountain-'pen having a slidable propelling-rod for projecting' and retracti ng' the pen, said rod being rotatable in its extended position, and means for preventing' the rotation thereof in its retracted position.

9. A fountain-pen having a propelling-rod provided with a member movable therewith, and a stationary member to cooperate with said movable member, said members having' abutting surfaces to prevent rotation when said propelling-rod is in its retracted position.

10. A fountain-pen having a barrel, a propelling-rod, a cap, and internally and externally threaded means secured to said cap to permit engagement with said propelling-rod, and also with the feeding' end of said penbarrel.

ll. A fountain-pen having' a barrel, a cap, a slidable propelling-rod moved thereby, and means to permit securing said cap over the feed end of said barrel.

l2. A fountain-pen having a slidable projiielling-rod and a single barrel-closure, propelling-rod-actuating member.
